To all whom it may conce/m.'

Be it known that l, FonREsT A'. HEATH, a citizen of the United States, and a resident of the city of Je sey City, in the county of Hudson and Stat of New Jersey, have invented certain new and useful Tmprovements in Mixing Devices, of which the fol-4 lowing is a specification. l

The object of this invention is to provide an improvement in mixing devices for thoroughly mixing or commingling the elements in a mixture such as issues from the delivery port Vof a carbureter in order to make it homogeneous, prior to being introduced into the cylinder of a hydrocarbon engine.

ln application Serial No. 496,266, filed May 15th, 1909, in application Serial No. 590,266, led November 2, 1910, (which is a division ofapplication SerialNo. 496,266), and alsok in application Serial No. 538,041, filed January 14th, 1910, l have shown a mixing device having a casing anda rotatable member therein comprising a fan member and a wire mesh, which is parallel with the path of rotation of the fan, for causing a disintegration of the particles of fuel in the mixture and a thorough commingling of. the fuel withthe rest of the mixture by a contacting of the wires in the mesh with the fuel particles as the mixtures pass the mesh and ata time when the rotatable member is rotating.

lt will be noted that the mixing device disclosed in any -oneof said v applications has only one mesh and therefore the wires in said mesh must be close enough together to cause a proper commingling and mixing of the fuel particles with the rest of the mixture as the mixture passes through the mesh. It will furthermore be apparent that the greater the number of wires which are in the mesh, the more effective will be the commingling of the fuel particles with the rest of the mixture and at the same time correspondingly greater will be the resistance of the passage of the mixture through the mesh. y

In order to more eectively mix or commingle the fuel particles with the rest of the mixture and at the same time decrease the resistance to the low of mixture through the mesh, l have lprovided a plurality of.

spaced wire meshes in which the distances between the wires are comparatively` great, whereby the' areas of the openings in the mesh are comparatively large and accordingly the resistance to the flow of mixture therethrough is correspondingly small. At `the same time l accomplish more e'ectively the mingling of the fuel particles with the rest of the mixture by successively subjecting the mixture to the cutting action of the outwardly extending wires or members arranged along its path of travel.

It is to the above features that this invention is particularly directed.

As showing a specific embodiment of my invention, reference is made to the accompanying drawing which forms a part of this specication and in which drawing- Figure 1 is a plan View partly in section showing one form of mixing device; Fig. 2 is a sectional view taken on the line 2 2 of Fig. 1; Fig. 3 is a plan view of the rotatable mixing member utilized in the device shown in Fig. 1; Fig. 4 is a plan vie'w of the rotatable mixing member utilized in the device shown in Fig. 1 looking at the member fromv below; Fig. 5 is a plan view partly in section showing another form of mixing device; Fig. 6 is a sectional view taken on line 66 of Fig. 5; Fig. 7 is a plan view of the rotatable mixing member utilized in the device shown in Fig. 5; Fig. 8 is a plan view of the rotatable mixing member utilized in the device shown in Fig. 5 looking at the member from below. l

Both forms .of the device shown on the drawing are similar in that each comprises a casing and a rotatable mixing memberl mounted therein comprising a fan and a plurality of spaced' meshes,'but the meshes shown in the forms illustrated in Figs. 1 to 14 have a different construction from that in the forms illustrated in Figs. 5 to 8. In the form shown in Figs. 1 to 4 a designates the casing in which is revolubly mounted the mixing member Z) comprising the fan member c which serves as a propelling member. and spaced wire meshes d and e located upon opposite sides ,of the fan blades. ln

this form the meshes d and e are composed t of straight wires f and g and la, and k respectively which cross each other and it will be noted that all the wires which compose the meshes have sections which extend tomesh and will therefore cause 'a thorough mixing and eommingling of the fuel particles with the rest of the mixture. The form shown in Figs. 5 to 8 has a casing a and a revoluble mixing member b which comprise a fan member 0' which serves as a propelling member, and spaced meshes d land ef located upon opposite sides of the fan concentric rings g have but little cutting orchopping eiect upon the mixture and 1t is obvious that without departing from the spirit and scope of my invention that the concentric rings may be omitted provided the outwardly extending wires or members are rigid enough and secured so as to remainl in place when the mixing member rotates.

It is obvious that various other forms and modifications may be made without depart- 'ing from the spirit and scope of -my invention.

I claim as my inventlon: l 1. A mixm devlce for hydrocarbon en` gines eomprislng a casing and a rotatable fan member therein by which the mixture.

passes and outwardly extending disintegrating or cutting elements which are located at the opposite sides ofthe fanand'rotatablel therewith.

2. A mixing device for hydrocarbon engines comprising a casing' and a rotatable blade propeller member therein by which the mixture passes and meshes securedto oppositev sides of the propeller'blades and rotatable therewith.

3. A mixing device for hydrocarbon en- I-gines comprising a rotatable blade propeller having spaced parallel meshes or screens secured thereto and rotatable therewith.

4. A mixing device comprisin a rotatable member having propelling bla es-for causing rotation of the member and rotatable with the blades outwardly extending disintegrating wire members which are located in thelpath of the mixed fuel and air which `pass the propelling blades, the said outwardly extending members being spaced apart and located at dii'erent points along the axis of rotation of the rotatable member.

5. A mixing device comprisingarotatable memberhaving blades and means carried by the member for engaging particles of fuel in the mixture passing over the blades, said means having wire members which extend 'toward the periphery, said members arranged so that they traverse the mixture at different points along its path.

6. A mixing device comprisinga rotatable member having outwardly extending blades, disintegrating or cuttin members located at opposite sides of the b ade carried by the blade and extending toward the periphery of the same and means for 'supporting the rotatable member in the piping of a hydrocarbonengine.A y

7. A mixing device comprisingarotatable member having blades, wire meshes carried by the member and located upon opposite sides of the blades, said meshes being flat and lying in spaced parallel planes.

. 8. A mixing device comprising 1n combination a. rotatable member having fan. blades for'propelling'the same and located in the path of the mixture passing the fan blades, said device also comprising rotatable -flat spaced screens which are arranged .at

of said member.

9. A mixing device comprlsingarotatable A.member having fan blades, said member carrying spaced meshes havingoutwardly extending spaced elements, said`meshes loldifferent places along the axis of rotation cated in the path or iow of the mixture, the

area of .the opening of the meshes being greater' than the area occupled by the wires 'or members which form the meshes.
